Since the bike allows you to prop up a phone or tablet for streaming cycling workouts, we're able to choose any apps we like. I opted for the Peloton Digital app ($13 per month), which gives me access to a library with thousands of on-demand classes that I can play in that moment or preload for later. And for days when I don't want to hop on the bike, there are also classes for running, walking, strength training, outdoor workouts, yoga, meditation, and abs.
